The Brundage mountain webcam is showing 8 inches of new snow this morning. This new snow is warmer and heavier, and has now created an upside down snowpack. The surface will be much denser than the older snow beneath it, making for difficult skiing and riding conditions. Human triggered avalanches will be likely as we now have a classic bad recipe of a strong layer over a weak layer.
Temperatures are already 10-12 degrees higher than yesterday. As the temperatures rise this afternoon, rain is forecasted to fall up to 6,000 feet which will increase the possibility of natural, loose-wet avalanches. Human triggered wet-loose avalanches will be likely in the lower elevations.
Winds have primarily out of the West, Southwest over the last 24 hours which have been doing a fair job of loading Northern aspects, creating wind slabs. Terrain features help to create swirl and thus cross-load, and load various aspects, not just the Northern aspects.

The Friends of the Payette Avalanche Center (FPAC) needs YOU! We are in desperate need of more user support and financial assistance. The avalanche forecast is not a guaranteed service, and is in jeopardy of dwindling down to only a couple of days a week in the near future.We have equipment that is overdue for replacement but lack the funds to purchase new gear including weather station parts and our forecast sleds. Please help if you can by clicking the DONATE tab above. If you value this life saving information, make a donation or help the FPAC in raising funds for the future.
Yesterday, on Slab Butte we observed significant cornice growth, and kicked off sizable pieces of overhanging cornices with our skis on the East ridge around 8,000 feet. We were also able to get some cracking in the shallow wind slabs on the ridge just to the South of the Face.
If you see or trigger an avalanche please let us know. These observations are crucial to our forecasts. You can send us an email at: email@example.com or better yet take 5 minutes and submit your observations through our website. Photos, aspect, elevation, trigger type and depth will help us get the word out and may save a life.
